Young Brunette Girl Posing In The Kitchen

Restaurant and canteen kitchens found in hotels, hospitals, educational and work place facilities, army barracks, and similar establishments are generally (in developed countries) subject to public health laws. They are inspected periodically by public-health officials, and forced to close if they do not meet hygienic requirements mandated by law.
Canteen kitchens (and castle kitchens) were often the places where new technology was used first. For instance, Benjamin Thompson's "energy saving stove", an early-19th century fully-closed iron stove using one fire to heat several pots, was designed for large kitchens; another thirty years passed before they were adapted for domestic use.
Today's western restaurant kitchens typically have tiled walls and floors and use stainless steel for other surfaces (workbench, but also door and drawer fronts) because these materials are durable and easy to clean. Professional kitchens are often equipped with gas stoves, as these allow cooks to regulate the heat quicker and more finely than electrical stoves. Some special appliances are typical for professional kitchens, such as large installed deep fryers, steamers, or a bain-marie. (As of 2004, steamers — not to be confused with a pressure cooker — are beginning to find their way into domestic households, sometimes as a combined appliance of oven and steamer.)
The fast food and convenience food trends have also changed the way restaurant kitchens operate. There is a trend for restaurants to only "finish" delivered convenience food or even just re-heat completely prepared meals, maybe at the utmost grilling a hamburger or a steak.
